Bitumen and bituminous binders - Determination of the resistance to hardening under the influence of heat and air - Part 3: RFT Method
This European Standard specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder, simulating the hardening that a bituminous binder undergoes during mixing in an asphalt mixing plant.
The method is referred to as RFT, i.e. Rotating Flask Test.
WARNING — Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
If there is a likelihood of volatile components being present in a binder, this procedure should not be used. It should not be used for cut-back bitumen or bituminous emulsions before these products have been stabilised, e.g. in accordance with EN 14895.

Bitumes et liants bitumineux - Détermination de la résistance au durcissement sous l'effet de la chaleur et de l'air - Partie 3 : Méthode RFT
La présente Norme européenne prescrit une méthode qui permet de mesurer les effets combinés de la chaleur et de l'air sur un film mince de bitume ou de liant bitumineux. Elle simule le durcissement que subit un liant bitumineux au cours du malaxage dans une centrale d'enrobage.
L'essai est désigné par RFT, ce qui signifie : Rotating Flask Test.
AVERTISSEMENT - L'utilisation de la présente Norme européenne peut impliquer l'intervention de produits, d'opérations et d'équipements a caractere dangereux. La présente Norme européenne n'est pas censée aborder tous les problemes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de consulter et d'établir des regles de sécurité et d'hygiene appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
Si la présence de composés volatils dans le liant est probable, le présent mode opératoire ne doit pas etre utilisé. Il peut etre utilisé pour les bitumes fluidifiés ou les émulsions avant la stabilisation de ces produits.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders - Sampling bituminous binders EN 1425, Bitumen and bituminous binders - Characterization of perceptible properties EN 1426, Bitumen and bituminous binders - Determination of needle penetration EN 1427, Bitumen and bituminous binders - Determination of the softening point - Ring and Ball method EN 12594, Bitumen and bituminous binders - Preparation of test samples EN 12596, Bitumen and bituminous binders - Determination of dynamic viscosity by vacuum capillary 3 Principle A moving film of bituminous binder is heated in a rotating flask of a rotary evaporator at a specified temperature for a given period of time. The effect of rotation is that material forming on the surface of the sample in the flask is constantly replaced, preventing the formation of a skin. The effects of heat and air are determined based on the change in mass (expressed as a percentage) or as a change in the bituminous binders’ characteristics such as penetration (EN 1426), softening point ring and ball (EN 1427) or dynamic viscosity (EN 12596), before and after hardening. 4 Apparatus Usual laboratory apparatus and glassware, together with the following:
EN 12607-3:2007 (E) 5 4.1 Rotary evaporator, capable of maintaining a rotational speed of (20 ± 5) r/min, used in conjunction with a 1 000 ml round bottom flask with a 29/32 ground cone socket. NOTE Cooler and receiver are not required. 4.2 Flow control device, capable of maintaining an air flow rate of (500 ± 10) ml/min at ambient temperature. NOTE To eliminate the effects of oxidation reactions, the air can be replaced with inert gases such as nitrogen. 4.3 Flowmeter, capable of measuring the airflow at a rate of 500 ml/min with a maximum indication error of ± 5 ml/min. 4.4 Thermometer, solid stem, as specified in Annex A. Other temperature measuring devices may be used instead of mercury stem thermometers, however, the mercury stem thermometer is the reference device. Therefore, any alternative device employed shall be calibrated to provide the same readings as would be provided by a mercury stem thermometer, recognising and allowing for changed thermal response times compared with a mercury thermometer. NOTE When measuring and controlling nominally constant temperatures as in this test method, alternative devices can indicate greater cyclic variations than mercury thermometers to an extent depending on the cycle time of heating and the power of the controlled heat input. 4.5 Glass air inlet pipe, approximately 400 mm long and with an inside diameter of 7 mm, mounted along the axis of rotation of the flask, as
